我首先下载了ubuntu-22.04-server-cloudimg-arm64.img，然后我用qemu启动它
qemu-system-aarch64 -m 2G -M virt -cpu max -bios /usr/share/qemu-efi-aarch64/QEMU_EFI.fd -drive if=none,file=ubuntu-22.04-server-cloudimg-arm64.img,id=hd0 -device virtio-blk-device,drive=hd0 -device e1000,netdev=net0 -netdev user,id=net0,hostfwd=tcp:127.0.0.1:5555-:22 -nographic -cdrom cidata.iso
它在这里失败了：
[ 159.518738] EXT4-fs (vda1): re-mounted. Opts: discard,errors=remount-ro. Quota mode: none.

这个错误是意外的，是不是图像损坏了？
